Calcium chrolide kits accurately measure the amount of moisture (in lbs) emitted in vapor by a concrete slab. Vapor emissions testing is the most widely accepted method to determine the moisture content emissions of a concrete slab.
- Highly recommended & required before installing hardwood and bamboo flooring over a concrete slab
- Inexpensive and easy to use
- Most accurate and widely accepted quantitative test method
- Peace of mind against liability for installation failures due to moisture
- Helps determine the level of vapor barrier needed when comparing flooring adhesives
- Meets ASTM F1869-16a standard
This test kit includes:
- A pre-weighted plastic jar with an airtight snap-on lid containing anhydrous calcium chloride
- A transparent plastic cover with pre-applied adhesive to create an airtight seal over the subfloor
Instructions for use:
- Using a scale that measures in grams, confirm the weight of the calcium chloride prior to testing
- Follow the included instructions to properly prepare the calcium chloride for the 24 hour test
- Weigh the calcium chloride after timed exposure
- Calculate your results using the Concrete Moisture Emission Calculator.
If our website lets you add your desired quantity into the shopping cart without showing a "this item is back-ordered" pop up notification, that means the product is in stock and ready to ship!
We highly recommend reading our Shipping Policy for a comprehensive explanation of our shipping processes.
We ship most freight orders (over 125 lbs) out within 4 business days of purchase, the average being 2 business days. For faster shipment of freight orders, we offer an Expedited Shipping option at checkout however please note that this simply means that we will ship the order out the next business day - it does not shorten the transit time once shipped. For small parcel orders we offer express UPS shipping options at checkout as well; please note that for express shipping services the order must be placed by 2pm EST in order to ship out that same day, otherwise we will process the shipment the next business day. We do not ship out orders, nor do the shipping companies deliver them, on weekends.
For residential lift-gate freight order deliveries, once the flooring order arrives at the local freight terminal, they will call you to schedule your delivery appointment, which is usually a 2-6 hour window on the day of your choosing (weekdays only) when possible. All deliveries are curbside as the freight companies do not offer inside delivery.
- You can purchase right on this website: add your desired items into the shopping cart, then click the cart icon at the top right of the website and click the "Proceed To Checkout" button.
- You can send an email with your desired materials list or purchase order to [email protected], and our support team will email you a quote with a payment button.
- You can call our support team directly at (301) 498-0234 and place your order over the phone.
None of our products are brought inside the delivery location by the driver. All small parcel shipments are at the discretion and policy of the shipping company. All freight shipments are curbside delivery with lift-gate unless you specifically request freight dock delivery. Curbside delivery means they lower the pallet on the street at the end of the driveway. The drivers are not required to enter the property boundaries, although if not hazardous sometimes they’ll back up the driveway (if it’s flat and short) and drop the pallet on the driveway. Someone must be on-site to receive the delivery and inspect it for exterior damage, and then note any damage on the driver’s bill of lading (otherwise we can’t send free replacements). We highly recommend that you do not pay laborers to sit around and wait for the delivery, as the freight companies do sometimes miss appointments and they do not reimburse for such lapses. In some cases at the time of checkout, our website will allow you to add "Garage Delivery" for an additional fee, but this includes rolling the materials pallet into a carport or garage only, and terms and conditions apply.
Yes, we sell several different products that provide sound insulation - underlayment and adhesive. To see these products visit our Installation Supplies page and check out our underlayments and adhesives. Many condominiums have sound insulation requirements for flooring. There are two sound tests that are the industry standard for sound insulation: IIC and STC. We have ratings as high as 83 STC and 85 IIC for underlayments and as high as STC 70 and IIC 66 for adhesives. The biggest benefit to using our high STC/IIC underlayments and adhesives is that you do not need to buy cork or other soundproofing and then pay someone additional to install it. Just float the flooring over the underlayment or glue the floor down using the sound reduction adhesive and you can substantially reduce sound transmission between levels in your home as well as muffling sounds from footsteps.
FLOATING FLOORS. In order to choose the right underlayment you have to ask yourself two questions: Do I need moisture protection, and how much am I willing to pay for sound reduction. When installing over concrete or over a crawl space, an underlayment with a moisture barrier (usually a thin layer of plastic or foil) is a must-have. This protects your wood floor from moisture rising up and damaging your floor from beneath. These are called 3 in 1 underlayment.
What are the 3 features of a 3 in 1 underlayment?
1) Moisture/vapor barrier
2) Impact absorption and sound transfer reduction
3) Cushioning for comfort
Remember that you will still need your sub-floor to be very flat before you begin the installation, as the underlayment only accounts for minor sub-floor imperfections. The second question having to do with how much sound reduction you want is simple - all underlayments have STC and IIC ratings that tell you how much sound they block. The lower the rating, the higher the echo or knocking sound when you walk on the floor. Underlayment with a 70+ STC and IIC rating will muffle noise much better than an underlayment with a 50 STC rating. As you may have guessed, underlayments with higher STC and IIC ratings are more expensive due to the quality of the materials or thickness of their construction.
Yes, we may be able to accommodate this, but please note that we may still apply a small shipping and handling fee to your order. Please reach out to your sales representative for details.
Yes! Some adhesives will fail spectacularly if you use the incorrect trowel size and design, so using the correct trowel(s) is a must. We currently sell two types: 1/4" x 1/8” Square notch for our basic urethane adhesive (no vapor or sound retarder) and a 1/4" x 1/4" V-Notch trowel that is used with our urethane adhesive with sound and vapor retarder. The V-Notch is designed to provide a thicker layer of adhesive so you have a complete layer/seal on the slab. Pro Tip: don’t skimp when troweling down vapor barrier adhesive or your floors will cup later! The Square notch trowel puts down about 85% coverage which is enough to hold down the floor on plywood or places where a sound and vapor barrier isn't required.
Absolutely. We’ve shipped our floors to such far-flung locations as Guam, Kenya, Tanzania, Bahrain, Great Britain, Kuwait, France, Mexico, Canada, Hawaii, and many more. Please note that international shipments may require you to procure the services of a freight forwarder at the port of discharge; most port authorities can provide recommendations for reputable freight forwarders that service your home port. Also, minimum order quantities may apply to some countries. Call your Ambient representative today at (866) 710-7070 for shipping quotes to your country!
Only an 18 gauge cleat nailer should be used to nail down strand woven bamboo and eucalyptus flooring (along with 18 gauge cleats). If you use 16 gauge cleats they are likely to cause dimpling on your floors as described in this article.
Furthermore, using any cleat or staple other than an 18 gauge cleat may cause cracks and splits in the tongue that will cause further issues down the road.
Some of our floors and plywood contain the densest hardwood material in the world (strand woven bamboo) and will wear down standard saw blades pretty quickly. For this reason, we recommend a minimum 80 tooth tungsten carbide saw blade. Diablo is a brand that sells such a blade (check your local big box store or online). Plywood tip: if you get burn marks on some of your cuts you can sand them off saw using a few stages of different high grit sandpaper.
At Ambient we value the brave men and women that serve in our nation's armed forces and law enforcement agencies. We offer a 5% discount off all products for active-duty members of our U.S. armed forces and full-time local and state law enforcement. Clearance items and odd lots do not qualify for this discount and it cannot be combined with other promotions.
For flooring and plywood we strongly recommend ordering a sample before placing your final order, so you can ensure that the shading will be to your liking. Our flooring and plywood samples have a dye lot number sticker on the back of them. Our website checkout process will ask you to type in this dye lot number before final payment; alternatively, if ordering via email or over the phone simply mention this lot number to your Ambient representative and we will update the order with it and ship that exact lot number. If we don't have that lot number available (it has sold out) but we have a matching lot, we will ship the matching lot. If we do not have a matching lot, we will not ship your order until you approve samples of the new lot.
Please remember that photographs on our website are taken from a variety of devices and under many different lighting conditions, and are viewed on a wide range of computer monitors and contrast settings, thus we do not guarantee that any floor will match the photographs on the website. If you order your flooring sight unseen (without receiving samples first), Ambient is not responsible for light or shading variation or differences and thus not responsible for return shipping costs (which can be expensive and can vary greatly depending on where you live and the size of your order).
If you receive the order from the exact lot number you requested, or you order sight unseen (you do not provide a dye lot number at checkout), and you decide after it arrives that you want to return the order, you will be responsible for return shipping charges. For flooring orders, please see our 30 Day Money-Back Guarantee for more information.
For legal businesses that qualify as a trade account (must be in the building trades), or you plan to order more than $10,000 cumulatively in building materials in the future on multiple projects, we encourage you to apply for a trade account on our B2B page. Our wholesale discounts vary depending on sales volume and can range from 5% to 35% off our retail prices. We also offer container level pricing for large projects at extremely competitive prices, and can manufacture a large array of products not featured on our website such as custom thicknesses, lengths, widths, colors and surface treatments (minimum order quantities apply).
